The company also announced that a planned figurine of popular Russian fighter Fedor Emelianenko has been delayed and will not be part of the Series 4 this summer.

"We continue to work closely with Fedor and his team on making his figurine as accurate and true to his persona as possible," Round 5 President Damon Lau stated. "Consumers appreciate Round 5's commitment to producing collectibles that capture each athlete's individual style, and we look forward to completing the Fedor figurine with that goal in mind."

Series 4, expected to be in stores by no later this early August, now features Gina Carano, Dan Henderson, Cung Le, Mauricio "Shogun" Rua and Matt Serra.

Series 5 will be released by year's end, though participating fighters have not been announced.

Round 5's offerings can be purchased at leading retailers such as Walmart (Canada), Toys 'R' Us, FYE, Century Martial Arts, Sunrise Records, The Treadmill Factory and Hatashita International. Other retailers can be found at www.round5mma.com/wheretobuy.php.
